Sidense to Deliver OTP Cores in UMC's 90nm and 65nm Process Nodes

OTP memory IP supplier to provide a path to cost reduction to SoC designers
OTTAWA, Canada, and HSINCHU, Taiwan - April 25th, 2006 - Sidense Corp., a provider of One-Time-Programmable (OTP) memory intellectual property (IP) and UMC (NYSE: UMC, TSE: 2303), a leading global semiconductor foundry, today announced that Sidense's 1T-fuse™ family of embedded OTP cores are slated to be silicon-verified in UMC 90nm and 65nm processes through UMC's IP Alliance Program and offered for use to system-on-chip (SoC) designers. The cores are scalable to UMC's CMOS processes without requiring additional mask or processing steps, providing users with shortened time-to-market and a path to cost reduction for their current and future designs.

The OTP cores are scalable across UMC's CMOS processes and easily ported across other technology nodes, such as 110nm and 80nm, potentially providing customers with several generations of continuous SoC migration. Sidense's high density macros can also be parameterized to obtain different configurations and can be used to replace external FLASH and EEPROM as well as a field programmable alternative to MASK ROM.

"As the demand for embedded OTP cores continues to increase, we are pleased to partner with a world leading foundry such as UMC," said Xerxes Wania, President and C.E.O. of Sidense Corp. "We continue to work with UMC to provide OTP solutions to customers looking for an OTP core targeted at low and high density applications. SoCs for printers, cameras, set-top boxes, mobile and handheld devices can benefit from the high density, secure and low power characteristics of Sidense's 1T-Fuse™ OTP offering."

In January, Sidense announced its OTP core targeted towards UMC's 130nm standard logic digital CMOS process.

"UMC's extensive portfolio has become a strong competitive advantage for customers designing today's sophisticated SoCs," said Ken Liou, director of the IP and Design Support division at UMC. "Sidense's technology is a welcome addition to our IP Alliance Program, as it will provide designers with a silicon proven OTP option for their 130nm, 90nm and 65nm designs. "
